That's an unstable process on a long-term, with popular topics
cannibalizing resources. Top read articles are already about two or three
sports, some TV series and three or four music topics.

resources to be spent on "female combatants during Russian civil war",
"near to extinction languages in Brazil", "computational chemestry in late
XX century".
